I spoke to a doctor today about a particular one that is painful to wear shoes where is rubs. It's not very big. Anyway, she asked me if I had any more and I said yes I have a couple of tiny ones on that same leg on the calf (really not that noticeable) and a few on both thighs. She seemed concerned and said it might need to be looked into! I said, don't most people my age (40) have some? She didn't seem to agree with that so just wondered if I am right or is it to be taken seriously?
